White Center's housing stock centers on 1975, which puts a lot of doors here on track hardware and roller brackets that have never been touched since the house was framed. Fifty years is a long run for galvanized track and steel brackets that were fine for the lighter doors common when the neighborhood was built. Track alignment shifts as houses settle, and on a bracket that's original to a 1975 build, the fasteners have often loosened just enough that one hard gust or one bump from a car bumper walks a roller clean out of the rail. With 5,742 households in this pocket and a median income of $82,500, most owners here are keeping the original door rather than replacing it outright, which means the same worn brackets get restressed instead of swapped. That's the pattern behind most off-track calls we see from this area: not a broken door, but fifty-year-old hardware finally giving up under a door it was never resized for.
